Figure 1 is a perspective view of my guard secured to the thumb of aninfant. .Figure 2 is a plan view of mg guard. Figure 3 is a side view oft e'same.

Figure 4 is a perspective view of a slightly modified form of myinvention.

Referring more particularly to the draw ing, a flexible tube 1. which ispreferably formed of rubber tubing, is secured to the thumb or finger ofthe infant. A ring 2 is secured to thetube 1 adjacent the upper. endthereof, and the ring as shown.
